Title: A process for the production of lasts for footwear
IPC: A43D3/02
Filed: 1946-09-17
Abstract: 640,702. Lasts. PELANT, V. Sept. 17, 1946, No. 27850. [A Specification was laid open to inspection under Sect. 91 of the Acts, Sept. 17, 1946.] [Class 17(i)] In copying a group of lasts from a master last on a copying machine, 'the dimensions of the fore part up to approximately the centre are made proportional to the variation of size from the master last, and in the rear half the heel periphery and length are varied non-proportionally with the variation in size. Approximately one quarter of the difference in length is allotted to the forward and rear thirds of the last and the remaining half to the middle third to lengthen the foot-arch portion. A comparison of such a last, drawn in full lines, with a master last as normally used, shown in chain-dotted lines, is shown in the figure, the differences in form under the arch and across from heel to instep being; indicated. The Specification as open to inspection under Sect. 91 states that the reduced increase of widths in the heel portion as well as the uneven distribution of the increments of length in relation to the entire length of the last, which render the lasts of a series not in the same proportion at all parts as in the master last, as is usual, render necessary adjustment of the milling cutters of a last copying milling machine version of a copying milling machine, Moreover, feelers employed for the milling cutters of a copying machine for making a series of lasts are of a diameter of 5 cm. (2 inches) or less in order to obtain a finer finish than is obtainable with the cutters of 10-20 cm. (4 to 8 inches) hitherto used. This subject-matter does not appear in the Specification as accepted.

Abstract: 616,604. Dispensing liquids. HORTON MANUFACTURING CO., Ltd., HALL, F. J. S., and RILEY, W. J. Oct. 25, 1945, No. 28184. [Class 102 (i)] A dispensing tap for liquids, e.g. liquid soap, comprises a piston 11 which is reciprocated in a cylinder 1 by a handle 12 and a returning spring 13, the movement towards the soapsupply conduit 7 forcing the soap through passages 31, 32 to lift the valve 33 and to pass into the space 9, whilst movement of the piston in the opposite direction closes the valve 33, opens the valve 19 and forces the soap through the outlet 30. The inlet 8 of the cylinder 1 is controlled by a valve 15 loaded by a spring 37, and the valve 33 is loaded by a spring 36 bearing on a collar 34 fixed on the rod 10. The valve 19 seats on a washer 24 clamped in position by the sleeve 18 and gland nut 4. The collar 34 seats on a packing disc 25 and assists the valve 19 in sealing the outlet 22. If the cylinder 1 is removed from the supply pipe 7, the valve 41 in the connector 6 closes under spring pressure, and the loss of soap is avoided. A filter 39 having a stem 40 opens the valve 41 when the cylinder 1 is again screwed into place. The tap, or a number of taps, may be supplied from a remote reservoir, or the reservoir may be made unitary with the tap or taps. The soap may be supplied by gravity or by a pump, or by both.

Title: Carbon electrodes for high-intensity arc lamps
IPC: H05B31/00
Filed: 1953-10-13
Abstract: 745,586. Arc lamps. GRETENER, E. Oct. 13, 1953 [Oct. 14, 1952], No. 28200/53. Class 39(1). Carbon electrodes for arc lamps have ends 14, 5 fitting one into the other, at least one of the ends being coated with an organic cement 6, 7 which undergoes hardening on heating due to a thermosetting process. The cement 6 can be a thermosetting material such as the phenolic resin Resol, alkyd resins, ethoxyline resins or shellac (stated to be thermosetting at temperatures above 400‹ C.) and the cement 7 can be a non-thermosetting phenolic resin such as Novolak. The cement may have an admixture of carbon, e.g. fine grain graphite, to ensure a high electrical conductivity and strength of the hardened joints. The thermosetting cement is such as to leave carbon, with the production of minimum of gases, if decomposed by further heating after hardening, the remaining carbon structure having sufficient strength to prevent disengagement of the joint between the electrodes. The cement 6 can contain an excess of thermosetting accelerating agent and the cement 7 very little or no accelerating agent, the excess accelerating agent causing thermosetting of the non-hardenable cement 7 when the carbons are joined after heating. A heater 27 located at the rear of the positive carbon holder 23 for joining the carbons can be provided as described in Specification 725,726. The holder 23 can cool the carbon and contains a nozzle for directing an air jet 24 towards the arc. A resilient contact piece 25 is provided for current connection. The carbons are joined manually or automatically as the end 28 enters the heater 27. The carbons comprise a shell 2 and a core 3 which has an admixture of oxides and rare earths. Cements formed from tar or molasses are referred to in the Specification as previously known.

Filed: 1946-09-20
Abstract: 654,048. Thermionic valve circuits. SMITH & SONS (ENGLAND), Ltd., S. Sept. 20, 1946, No. 28307. [Class 40 (vi)] In a circuit for deriving an A.C. voltage modulated by the differential or integral of the modulation of a modulated A.C. input voltage, demodulation of the input, differentiation or integration of the modulation and modulation of the reference voltage by the differential or integral of the original modulation is effected in the same valve or valves. The Figure shows a circuit in which a component proportional to the integral of the amplitude of a modulated carrier is added to the modulation present on the carrier by applying it in push pull to valves V1 and V2 which are A.C. operated in the manner of a balanced demodulator so that the incoming carrier differentially varies the A.C. voltage difference appearing across the remote ends of the anode load resistors 16 and 18. An integral component is introduced into the modulation envelope of this voltage difference by degeneratively feeding back the voltages across the resistors via differentiating networks R1, C1 and R2, C2. The lower ends of resistors R1 and R2 are returned to taps on the resistors 16 and 18 respectively to provide a measure of regeneration to offset degeneration produced by cathode balancing resistor 8, variable resistor 20 controlling the amount of regeneration. The A.C. anode voltage difference is fed to the output by transformer 6. Differentiation may be effected by providing an integrating network in the feedback path, Fig. 2 (not shown). Specifications 621,473 and 674,823, [Group XXXV], are referred to.
